Hello,
Recently I have been making 10 gallon batches. Everything throughout the process is done in increments to yield 10 gallons of delicious Wort.
However, because I do not have a carboy large enough to ferment all 10 gallons I have been breaking it up into two 5 gallon glass carboys.
The first time I did this I noticed a huge difference in color between the first carboy and the second. The first 5 gallons was a beautiful golden color, similar to the last time I had made a 5 gallon batch of the same recipe. The second 5 gallons was a bit more dark bronze in color.
OG and FG of each were almost exactly the same. Upon finishing, there again the first 5 gallons retained its beautiful color had a nice white head, head retention, and exceptional taste. The second 5 gallons there again, a dirty bronze color, minimal head or retention and it lacked that killer taste of the first. Considering all 10 gallons came from the same boil kettle they were like night and day!
Since then, I have been breaking up the Wort in 1 gallon batches between two carboys in hopes of blending the 10 gallons or distributing its components more equally. Furthermore, when racking to secondary or keg, I have been using two racking canes and siphoning each carboy at the same rate to either the secondary or keg, there again in hopes that a simple blend of the two will create a better all around and similar product.
And now for my question: is what I am experiencing a common problem? And is my possible solution to the problem going to yield the same great beer 10 gallons across the board or now is all 10 gallons subject to the same potential undesirables?
